2 Claims. (Cl. 15-138) The instant invention relates to a cleaning andpolishing device and more particularly to a floor mop or brush havingthe cleaning or polishing fluid carried Within a hollow handle thereof,to be dispensed by the user as required.

One of the primary objects of the invention is to provide a floor mop orbrush of the character specified in which the cleaning or polishingmedium is carried in a replaceable cartridge insertable within thehollow handle of the mop or brush.

Still a further aim is the making of a mop having a replaceablecartridge holding a cleaning or polishing fluid, said cartridge having avalve mechanism readily operable by the user for dispensing the fluid tothe cleaning or polishing mop or brush.

Yet another aim is the construction of a device of the type indicatedhaving a perforated dispensing adapter readily attachable to both thehandle for feeding the polishing or cleaning medium and to the brush ormop.

An additional purpose is the construction of a cleaning or polishing mopor brush which will simplify the cleaning or polishing of floors; whichwill aid those allergic to dust; which will eliminate the necessity ofapplying cleaning or polishing liquid on the floor or to the brush ormop; which is simple in construction and has relatively few parts; andwhich may be manufactured at a comparatively small cost.

The above and other aims and objects will be apparent from the detaileddescription hereinafter appearing when taken in conjunction with theappended drawing forming a part hereof and showing a preferredembodiment of the inventionand in which Fig. 1 is a broken sideelevational view, partly in section, showing a brush or mop with thecartridge valve in open or dispensing condition.

Fig. 2 is a broken side elevational view of a replaceable cartridge.

Fig. 3 is a top plan view of Fig. 2.

Fig. 4 is a broken vertical sectional view, showing the manner in whichthe replaceable cartridge is mounted and held within the upper portionof the hollow brush or mop handle.

Fig. 5 is a perspective view showing the manner in which a perforateddispensing adapter may be secured to a brush or mop; and

Fig. 6 is a bottom plan view of the dispensing adapter of Fig. 5.

Referring to the several figures in which like reference charactersdesignate like parts, the cleaning or polishing device is generallydesignated as D and comprises a hollow handle H, a replaceable cartridgeC, a perforated adapter A and a brush or mop B.

The hollow handle H which may be of any desired length of tubular metalor plastic is provided adjacent the upper end thereof with an externalthread 10. Cartridge C comprises a cylindrical hollow main body portion11 of a size to hold an adequate quantity of cleaning or polishingfluid. The lower section 12 of the cartridge is provided with anintegral internal centrally perforated seat 13, said seat beingexternally threaded at 14 for removably receiving the internallythreaded end 15 of a tapered tip or nozzle 16 opens as at 17. Upper half18 of the cartridge C has an inwardly extending integral centrallyperforated seat 19 supporting an axially apertured disc 20; said upperhalf 18 being externally threaded at 21, see Fig. 4. An elongated valverod or stem 22 has one end thereof projecting through the aperture indisc 20, said rod terminating in a flattened head 23. Surrounding theupper terminal portion of stem 22 and resting on disc 20 is a coilspring 24; the flattened head 23 of the stem tightly fitting into andsecurely held within a recess 25 of a dispensing button 26, which inturn is held in place by a thin sleeve 27 internally threaded at 28 forengagement with the external threaded end 21 of the upper section of thecartridge body 11. Sleeve 27 has a central opening 29 through whichbutton 26 extends, said button having an internal annular flange 30adapted to abut the inner surface of the sleeve. Valve stem 22 isthreaded as at 31 for removable connection to valve disc 32 having athreaded opening 33.

It is intended that cartridge C hold a quantity of cleaning or polishingliquid to be sold as a unit. The cost of the dispensing valve mechanismembodied in each unit should be relatively small as compared to the costof the liquid contained Within the cartridge. However, if desired, thesingle cartridge may be refilled with a cleaning or polishing liquid forreuse, in a manner which will be more fully described hereinafter.

The cartridge C is placed within the upper portion of hollow handle H,whereby the lower edge of sleeve 21 rests on the upper edge of thehandlesee Fig. 4. Pinally, a thin internally threaded handle sleeve 34,similar to sleeve 27, threadedly engages external threads 10 of thehandle with button 26 loosely extending through a central opening 35 insaid handle sleeve. It will now be seen that the cartridge isoperatively held Within the handle.

Hollow handle H is internally threaded at its lower end as at 36 for thereception of the perforated hollow dispensing adapter A. The lattercomprises a perforated bottom wall 37, curved perforated side and upperwalls 38 forming a hollow container and a neck 39 externally threadedfor engagement with the internal threads 36 of the hollow handle.

A cleaning member comprising a brush or mop B is characterized by acloth head 40 holding bristles or mop strands 41. It will be noted thathead 40 has oppositely disposed spaced cloth pockets 42 and 43 intowhich the dispensing adapter is to be inserted in the manner illustratedin Fig. 5, one end of the adapter being first inserted into one of thepockets 42 or 43, and then into the other, the pockets beingsufliciently stretchable to permit this.

From the above description, it will be seen that the cartridge C and itsvalve mechanism, filled with cleaning or polishing liquid, may be soldas a unit, and after insertion into the upper portion of handle H, issecured in position by means of threaded sleeve 34. In this position,the cleaning or polishing device D may be moved along the floor or othersurface with brush or mop B in contact therewith. The user now depressesbutton 26 against action of spring 24, thus forcing valve disc 32 fromits seat as in Fig. 4, to the position of Fig. 1, whereby the liquidwill flow downwardly into the adapter A which distributes same by virtueof its perforations through porous cloth head 40 to the bristles or mopstrands 41. Release of pressure on button 26 obviously stops the flow.While it is contemplated that cartridge C with its valve mechanism besold as a unit and replaced in toto when all polishing or cleaningliquid has been used up,

yet it is possible to refill the cartridge by removing same from handleH, unscrewing tip or nozzle 16 and valve disc 32, inverting thecartridge and filling same through the central opening in seat 13.

It will be understood that various minor changes maybe made in thespecific disclosure and it is contemplated to cover all such and to belimited in this respect only as maybe necessary by the scope of theclaims hereto appended.

What we claim and desire to secure by Letters Patent 1. A cleaning orpolishing device comprising a tubular handle open at opposite ends, acleaning member, means for securing said cleaning. member to the lowerend of the handle, the upper end of. the handle being externallythreaded, a replaceable. cartridge insertable into the upper end of thehandle, said cartridge having a valve mechanism and a button foroperating said mechanism, an external sleeve secured to said cartridgeholding said mechanism with said cartridge, said sleeve resting on theupper edge of said handle, and a centrally apertured second internallythreaded. sleeve adapted to hold said cartridge Within said handle byengagement with the external threads of the upper end of said handle.

2. The structure of claim 1, in which said means for securing thecleaning member to the lower end of the handle comprises providing saidlower end with a threaded portion, said cleaning member including a headhaving oppositely disposed spaced pockets, a hollow adapter having aperforated bottom wall, curved side and upper walls and a threaded neck,said adapter being inserted into said pockets by virtue of the spacetherebetween, said threaded neck being in removable threaded engage mentwith the threaded lower portion of said handle.
